I have been batling with headaches since I can remember, age 3. Now I am 36, and it is just getting worst. It feels like a stabbing pain in the centre of my head. Pain between my shoulder blades and when I sit down and want to get up I am stiff in my lower back and needs to gradualy get upright. This is very painfull. I also hve kidney reflux and sometimes wonder if this is not a possible cause for my headache.
It may be a sinus, so antibiotics were given for your Frontal snius infection. Avoid allergens, avoid cold irritants, try to find out what is causing this. Go for an ENT examination and take some antibotics and anti inflammatory drugs. Take care!
